Why is it better to use other tungsten electrodes instead of pure tungsten electrodes for welding?

Science and technology have lead to greater revelations and drastically changed our lifestyles. Today, you have more powerful systems and appliances including gadgets that enables better efficiency and performance whatever we tend to do using them. It has revolutionized our lives. The newer power source technologies are way more powerful and efficient than the traditional ones that were once used for the same purposes. They give you better precision and perfection of end results. On this context, welding strategies have also been improvised with the use of higher quality welding equipments. Today, you have more stronger and sturdy welds being produced and the end products have certainly been very efficient and great. On this note, use of traditional pure tungsten electrodes for welding has decreased.

Pure tungsten has the ability to melt down at lower temperatures forming rounded ball at the tip of the welding gun. This ball as it grows in size during the welding obstructs the welder, not allowing focusing on the task. In fact it doesn't allow you to see the weld puddle and the arc which is very significant for producing proper welds goes unstable as a result. Predominantly you end up with poor quality welds.

Ceriated tungsten electrode on the other hand has tremendous capabilities to work in higher temperatures. It also works pretty well with the modern technologies such as the new squarewave and inverters used for providing stability of current supply. It holds the point longer and starts well at low amperages as well. It could be used for both AC as well as DC polarities. It allows welding amperages to be increased by 25-30% when compared to pure tungsten of the same diameter.

Thus predominantly, these days heavy manufacturing industries make use of ceriated, thoriated, lanthanated and zirconiated tungsten electrodes for carrying out welding processes.

Consumables are important components for manufacturing industries and the overall welding process.

Guns and Torches

There is a variety of welding equipment, which includes a wide range of guns, gears and torches. Each piece of equipment serves a different purpose. For example: MIG welding will require different equipment from plasma cutting processes.

Helmets and Safety

Investing in the right welding helmet is a smart and convenient way to enjoy added protection. Still, welding is a potentially dangerous activity, forcing welders to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light and radiation. Everlast safety helmets are thus a necessity for welders.
